The time span in the Probyn mysteries covers the years 1956 to 1972 - a time of civilized travel - and the stories take the reader to foreign locales including Portugal, Switzerland, and Ireland.
I bring this up because today Amazon has all eight of the Kindle editions of the mysteries published by Bloomsbury Reader (as well as other classic ones by Edmund Crispin, Margery Allingham and Nicolas Freeling) on sale for $1.99 each. I paid $7 for the first one in January 2012 when I was introduced to this globe-trotting heroine. So now it looks like I can get the remaining seven for only twice that much!
Ms. Probyn's adventures in North Africa led me to Edith Wharton's In Morocco, an account of her time spent there after World War I. Wharton stayed in the Bahia Palace, a fact mentioned in Ms. Probyn's tale.
A case of one book leading to another, or in this case, many others.
